provements in PlowingMachines, of which the following is 'a specification.

"In my pending application Serial No. 130,424, filed November 9,1916, I have described and claimed a plowing machine hava rapidly rotating plow or cutter mounted in a counterbalanced plow frame provided with gage wheels and arranged to be permitted a sidewise rocking movement as the gage wheels and plow are carried along, sprocket chain engaging an equalizing device connecting the parts of a divided shaft, and the two members of such'shaft being connected described, the

pended claims.

by sprocket chains engaging sprocket wheels on the ends of the shaft with sprocket wheels on the opposite ends of the cutter shaft. My present invention has the same general purpose as that described in my saidprevious application, and its main object is to provide a desirable machine, varying somewhat in construction and arrange-- ment from the machine of my said prior application, and in which the'motor which propels the machine and drives the rotary plow is arranged withthe motor shaft extending longitudinally of the machine; a

connection between agear on the'rear end of such shaft and a differential mechanism on a two-part shaft connected with the cutter permitting'a rocking sidewise movement of the cutter frame and associated parts similar' to that of the machine of my'prior application. With the; foregoing and incidental objects and advantages in View my invention consists in the construction, arrangement and organization of parts hereinafter essential elements of which are more particularly pointed out in the ap- -Figure 1 is a side elevamachine embodying my invention; Fig. 2 is a plan view 0 the same'; Fig. 3 is a central vertical section of the differential mechanism and plow frame and plow at the rear end of the machine; Fig. 4: is a cross section on the line of Fig. 3; Fig. '5 is a fragmentary longltudlnal vertical section'of a modified form of transmitting power to the difierentlal mechan sm,

In the drawings,

and Fig. 6 a similar view of another modi- T glhe frame 1 of my machine may be of any suitable .construction and arrangement of frame members secured together to form a structure adapted to support the parts of the machine and mounted upon a pair, of front guide wheels 2, and a pair of caterpillars each consisting of a pair of wheels 3 mounted in a rocking truck 4 pivotally connected with the frame andengaged by the rolling platform 5. Near the center of the frame 1 is arranged the motor'6, the front end of the motor shaft '7 being arranged to be connected through manipulation of a clutch 8 with a change-speed transmission mechanism, which, as such devices are well known and may indifl'er'ently beof one or another of various designs, need not be illustrated in detail and may be designated generally by the reference numeral 9 indicating the casing of such mechanism. The outer ends of the members of a divided cross-shaft 10, the

inner ends of which are connected by a differential mechanism arranged in cooperative relation with such change-s eedmechanism, carry a pair of sproc et wheels which by sprocket chains 12 are arranged to drive sprocket wheels secured to the rear wheels 3 of the caterpillar, in .order to proel the machine.

Suitable steering mechanism, operated by the hand wheel 13, is provided to direct the wheels 2 in unison and guide the machine.

The rear end of the motor shaft 7 is. also arranged to be connected by a sliding clutch 14 with a driving shaft element 15 which is in the present instance 0 '"peratively connected with a change-speed transmission deblock members 20 formed integral with a bracket plate or frame 20 extending across and secured to the its rear end.- The hollow axles or shaft supports 21 secured to opposite sides of the differential casingare equipped with antifricframe of the machine at tion rollers 22, and in their rocking-move chine is mounted to rotate in a U-shaped frame 26, the front end of this frame carrying on its cross-member 27 a pair of brackets 28 which rotatably engage the shaft su pports or hollow axles 21 secured to the differential casing 19. I

The rotary cutter or plow may suitably be of the same construction as in my prior application, and as in the machine there described the cutter. frame is counterbalanced by means block and tackle'mechanism connected to a cross bar 30, and cables 31 connecting the ends of such crossbar which the gear wheel 37 rotates.

with the sides of the cutter' frame 26, and the depth of cut of the plow is regulated by gage wheels 32 mounted on bearing lates 33 adjustably secured to the side members of the frame. A-bafiiing shield 34 is pivotally mounted concentrically of the axis of the of this shield is supported close to the sur face of the fground by a roller 35 carried by the front 0 the shield;

The shaft 17" above mentioned carries,=

within the diflerential'casing 19, a worm 30 arranged to engage the teeth of a gear Wheel 37 of a differential or equalizing mechanism, which may beef any suitable construction, such, for-instance, as those described in my prior application-above mentioned, or that illustrated in the accompanying drawings. As herein shown, the differential or equalizer comprises a series of rocking plates 38 carried by ings in said gear wheel upon pivots extend ing radially across such openings, and a pair of hubs 39v mounted respectively-upon squared portions of the inner ends of the members of the two-part axle or shaft 40 mounted 'in the shaft sup orts 21 and formed with radial pivot blocks 41 arranged to engage end slots in the rocking plates 38; he extreme inner ends of the members of the shaft 40 form a pivotal support upon The outer ends of the members of such shaft .are provided with. sprocket wheels 42 which by sprocket chalns 43 .are connected with sp' ocket wheels 44 on the opposite ends of the cutter shaft, completing the train of connections by which the cutter is rotated.

It will be understood that different variations and modifications of the structure above'described are possible without departing from my invention. 'For instance, as shown in Fig. 5, the driving shaft eleof a weight 29 connected through plow, and the front edge and pivotally mounted in opena rotary '20, corresponding to the parts 19 and 20 heretofore described, being modified accordingly. I 1

A different modification is shown in Fig.

6 in which a sprocket chain 47 operatively 1 connected to the motor is arranged to drive a, sprocket wheel 48 mounted in bearings secured to the differential casing 19?, a pinion 49 on the shaft of such wheel and in mesh with a gear wheel 50 which forms part of a differential mechanism serving to communicate power to such mechanism ;it being understood that the construction and -arrangement of parts associated with the modified forms of connection shown in. said Figs. 5 and 6 may be substantially the same as illustrated in Figs. 1 to .4, inclusive, and hereinbefore described.

While in t e above description and drawings I have'described the differential casing as formed, with trunnions, it is obvious that if preferred the hearing or supporting member carried by the frame may be formed in the trunnions ada ted to engage bearings forming in the differential casing, and I therefore regard such reversal of elements as an equivalent construction falling within the scope of my invention and claims.
